Hybrid analog/digital precoding is a promising technique to reduce the hardware cost of radio-frequency components compared with the conventional full-digital precoding approach in millimeter-wave multiple-input multiple output systems. However, the large antenna dimensions of the hybrid precoder design makes it difficult to acquire an optimal full-digital precoder. Moreover, it also requires matrix...
Millimeter wave (mmWave) communication system provides large unlicensed spectrum which helps to achieve huge capacity leap in the next-generation wireless system. The capacity is further improved by precoding technique in multiple-input-multiple-output (MIMO) transmission systems. Although the adoption of large antenna arrays in mmWave transceivers mitigates the huge path loss, it also increases hardware...
